THE BORGWARNER EFR 8474 TURBO BRING STATE-OF-THE-ART DESIGN AND POWERFUL PERFORMANCE

The EFR8474 represents the state-of-the-art from BorgWarner Turbo Systems. The winner of Pike's Peak Unlimited class for the last 2 years, 8474 is intended for applications that require an unmatched response and a broad powerband in the 500-800+hp range. 

Designed specifically to win races, BorgWarner engineering designed the 84mm compressor wheel with lower inertia than the 83mm it supersedes. The combination of a high flowing 68mm compressor inducer with a low inertia and quick spooling 84mm exducer allows the same footprint to breathe a LOT better up top without compromising low-end response and midrange torque.

Efficiency plateaus are widened as a result and higher pressure ratios can be better utilized. Using Borg Warner’s large inducer “black series” 84mm billet compressor (68mm inducer) the 8474 houses the EFR extended-tip compressor wheel design capable of 95 lb/min airflow rate. Using the same 74mm Gamma-Ti turbine wheel from the EFR8374, this turbo flows an impressive 95lbs/min of air at the same 127k RPM maximum shaft speed. That’s a 22% improvement in flow on the same turbo size! We strongly recommend using an EFR Speed Sensor if you plan to run this turbo to the limit (125krpm+).
